I purchased my DB2 last September and couldn't be happier. No, that's not completely true. It would have been nice if the previous owner had also had some of the little bits that would have originally come with the bike. Now I have to hunt down the following;
tool bag and kit
owner's manual (I have a pdf but want an original hard copy)
original bike stand that they came with
bike cover (I've been told they came with one but haven't been able to confirm that)

Looking forward to hearing back from anyone who has one of the above for sale or can point me in the direction of finding any. Thanks.

Workshop manual...again a photocopy for 50 euros...yet ditto comments as above (strictly speaking though...these were for the dealers use and not for handing out to customers..."one" wasnt supposed to service and tend to "ones" own Bimota back in the days...

Here are the leather key fobs, that fold over in half...and the tiny threaded brass pin holds the keys in place...and then you clip it in...these are "reproduced"...BUT...they are made in Italy by the same company that made the originals....from virgin cows fed only on fresh natural pastures basking in the Rimini midday sun

I quite like those and can confirm they are the same as the original...complete with the stamped logo

Wait...I haven't finished yet....Rear packing crate pop up stands do come up on ebay occasionally...but you have to then have made the pins to locate in the concentrics as evidently you cant push the normal rod through...because the DB2 has a solid and not hollow spindle....BCP (seller of all of the above...has no stands left)

Then....theres the gold Bimota "b" pin badge...but maybe just for bikes from the 80's....

Surely not more???? yup...one last item...that I've only ever seen photos of...a leather bound wallet folder in red hide....with a key locking front...with a silver plaque on the front with the exact serial number of the bike on it...

This is one of them...only 4 serial numbers away from mine

Then theres the wiring diagram

From the factory options list you could also order the carbon heel guard...and carbon wing mirrors

and then theres the titanium end cans just for the DB2

and lastly a pencil hand drawn sketch of your very own bike

Of course...I only know of one person who has all this bar the red leather folder...and all original copies...he can supply high res copies of the sales brochure and other stuff...which he doesnt charge for......but being as obsessive as perhaps yourself...its unlikely he'd sell any of the stuff...got to go now...but I'll dig out names of dealers that may be able to help you with original copies of the owners manual....also try Bob of Bimota spirit in the USA...he's provided originals of owners manuals for me before

Oh...you can also but these pin badges...which are made of metal and hand enamelled...said previous person also has one of these of course......Many of the trinkets given by Bimota to new owners is very evidently kept by the seller for nostalgia...or coz they've misplaced them...or sometimes more commonly, the new owner has "stolen" the bike at a cheap price...and thus the previous owner has held back on giving out the trinkets.........If I see any of the Original bits youre looking for I'll give you a shout privately.....I do have a spare tool kit though....wink wink...even the duster cloth that comes with it is still in its original sealed envelope.....TREASURE!!!!!!!!!!....

You may want one of these for your man cave...you should be able to click and print off whatever size you want

I should perhaps mention that I hope you are a patient and young or at least healthy man...it took me 8 years to collect all the pieces...my bike came with one ignition key and one petrol cap key...and no front discs!!!.......

This spare parts manual shows you the contents of the tool bag at the very end...and the actual rear bike stand and leather key fob...and the concentric chain adjuster tool....no bike cover is shown though

I did get the leather key cover a few weeks ago and I have found all the manuals (parts, owner's, wiring diagram, etc.) online for free which was great. I even found a couple of the original rubber fuel tank hold-downs which surprised me.
The parts I listed are just what I am missing from having the bike essentially complete. I guess it doesn't matter a lot as having the bike itself is the main thing. Still, it will be nice over the next few years to gradually find what I can.

Getting closer. I found an original hard copy of the owner's manual but not the nice leather case that would have originally come also. I found a tool kit with the bag but it's missing the shock adjuster and the 2-piece spark plug wrench. If anyone has a lead on those two items I would much appreciate it. I don't think I will try to find the stand as I have a really nice one anyway that is a nice red to match the frame and swing arm.

Last thing I need to really do is make the sidestand bracket that lets the sidestand stay down.
